COVER FOR BEET-FLUMES.

Specification of Letters Patent.

Patented May 25, 1909.

Application filed Octoberil'?, 1908. Serial No. 458,322.

To all whom 'it may concern.'

Be it known that I, JAMES R. LEES, a citizen of the United States, and a resident of Denver, in the county of Denver and State of Colorado, have invented a new and Improved toveiI for Beet-Flumes, of which the following is a full, clear, and exact description.

This invention relates to flumes such as are used in connection with beet sugar mills for floating beets into the mill from the receiving sheds.

The object of the invention is to produce a flume cover which will be very strong and durable, which can be simply constructed of metal, and which is constructed in such a way as to enable 1t to be readily removed, and if desired secured in position.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

`eference is to be had to the accompanying drawings forming a part 0f this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a perspective of a flume cover constructed according' to my invention; Fig. Q is a cross section of this cover; and Fig. 3 is a cross section through the fiume, and showing the cover applied thereto, the cover being shown in longitudinal section.

Referring more particularly to the parts, l represents the flume, and 2 represents the cover, which is constructed according to my invention. These covers are applied side by side so as to form a complete cover or deck over the flume. These covers are normally adapted to be raised so as to enable the beets to be thrown down the inclines or chutes 3 into the flume. The cover 2 is formed of light metal, which is adapted to be pressed or molded int-0 the form illustrated. lt consists of a rectangular plate, the material whereof is offset downwardly so as to form a plurality of longitudinally disposed ribs e on the under side of the plate. The ends of the plate are turned downwardly so as to form flanges 5, which reduces the bearing surface to a minimum, and these flanges are provided at suitable points with openings 6, by means of which the cover may be fastened, if desired. Near the middle portion of the cover, the ribs fl are spaced equidistant, as shown in Fig. 2, but near the side edges unusually wide spaces or side faces 7 are formed. In these side faces 7, openings or hand-holes 8 are formed, the edges of these openings 8 being pressed downwardly, as shown.

The covers are laid in place transversely of the flume, as indicated in Fig. Then it is desired to remove the cover, this may be done by applying a hook at the handholes 8.

On account of the reinforcing ribs 4, plates of very thin material may be used for forming the covers, as the ribs reinforce the plate and give it great strength and durability.

The covers will usually be left unattached, butl if desired, certain of the covers may be secured by fastening devices applied in any manner through the openings 6 in the flanges 5. Because the cover is supported on the flanges, the surface for the cover is greatly reduced, and this facilitates the removal of the cover in freezing weather. The openings 8 also operate to facilitate the circulation of air through the cover.

Having thus described my invention, I claim as new and desire to secure by Letters Patent,-

l. A- flume cover consisting of a metal plate having reinforcing ribs formed therein, and having means fo applying a lifting device to raise the cover.

2. A flume cover formed of a metal plate having downwardly projecting flanges on the ends thereof, and having openings in the body of said plate for applying lifting devices.

3. A fiume cover consisting of a metal plate having longitudinally disposed reinforcing ribs formed therein, and having flanges formed at the ends thereof.

4. A flume cover consisting 0f a metal plate having longitudinally disposed reintening devices, said cover having openings 10 forcing ribs formed therein, and having in the body thereof to receive lifting devices. flanges formed at the ends thereof, said ln testimony whereof I have signed my cover having hand-holes formed therein to naine to this specification in the presence of receive lifting devices. tivo subscribing Witnesses.
